Pressure dependence of transition temperature in selected high-Tc superconductors

Abstract
In this paper we report recent determinations of Tc(p) from the complex ac-susceptibility for both single- and polycrystalline Tl2Ca1Ba2Cu2O8 and Y1Ba2Cu3O7 using a helium gas system to 10 kbar and a hydrostatic metal—gasket cell to 35 kbar.
